Breastfeeding while pregnant

Hi mummies! I wanna ask, if any of you did breastfeed your lo while being pregnant? My lo is 1 yr old and is exclusively bf. He refused to take bottle and will cry bloody murder each time we gave him the bottle until no voice. I dont want to scare him any further and i observe that after the whole bottle feeding, he turns to be very clingy to the boobs and will cry for milk esp at night. Almost every 2 3 hrs wake up and cry for feed. Should I continue to just bf him? Isit possible? Is there any tips to help smooth the journey for me? Im almost 3 months pregnant now.
